Switch off the Daikin unit with the field supplied circuit breaker.3. Remove plate work when required (refer to "Basic removal" on page 67).4. Switch on the Daikin unit with the field supplied circuit breaker.5. Switch on the Daikin unit via the user interface.6. Check if the HAP LED is blinking in regular intervals (1/0,5 sec), if not blinking, replace the main PCB board (refer to "Replacingmain PCB" on page 89).7. Measure the supply voltage to the main PCB board: there should be ± 220 V between brown and blue cable. If not correctvoltage, replace the electrical noise filter PCB (refer to "Replacing electrical noise filter" on page 80).8. Switch off the Daikin unit via the user interface.9. Switch off the Daikin unit with the field supplied circuit breaker.10. Remove plate work when required.11. Open the compressor insulation.12. Remove the terminal cover of compressor wiring.13. Measure the voltage on S70: pin 7-4 and wait until it drops below 10 VDC.14. Disconnect the compressor wires and connect the compressor wires to the Inverter Analyzer (SPP number 1368521).Technical specification DescriptionLocationPiping diagram Wiring diagram Switch box Component overview of unitSee "Outdoor unit" onpage 117.See "Outdoor unit" onpage 115.See "Outdoor unit" onpage 122.See "Outdoor unit" on page 119.Check procedureMechanical checkElectrical checkWARNING : R ISK OF ELECTROCUTIONThe smoothing capacitor must discharge below 10 VDC before removing the compressor wiring.INFORMATIONNote the position of the cables on the compressor wire terminals to allow identical wiring during reinstallation.
